1

DNA replication is...

the method by which DNA is copied; semi-conservative

2

Contains...

parent template and daughter strand

3

enzyme that proofreads

DNA polymerase

4

occurs at the...

replication forks

5

enzyme that breaks down hydrogen bonds

helicase

6

1st step

helicase breaks bonds which unwinds the DNA molecule

7

2nd step

DNA polymerase adds complementary nucleotides to each strand of DNA

8

RNA contains

1. single strand instead of two
2. ribose instead of deoxyribose
3. uracil instead of thymine

9

pyrimidines

T,C,U (1 ring)

10

purines

A,G (2 rings)

11

mRNA

messenger; carries instructions for making proteins

12

tRNA

transfer; carry amino acids

13

rRNA

ribosomal; help form ribosomes
